In final stages of cabling our boat and looking for best solution to drop main battery voltage 48V to 24V for house use. Average daily house use around 2.5 kW with potential peaks of 2.6kW possible at times.
Could use three or four Orion-TR 48:24V 380W converters in paralell direct to load but imagine would over stress converters. I think better solution is to install a separate 24v lithium battery bank (around 2.8kw) as a buffer between DC converters and load - and use converters to keep this bank charged. It appears that Victron do not offer 48:24V B2B chargers.
Would three or four Orion DC converters 48V:24V 380W wired in parallel be suitable to manage house loads via the 24V batteries with a suitable BMS to stop and start converters?
It seems that this solution would provide sufficient amps into the 24V batteries but lack any charge stage cycling - maybe not best solution for long term life of batteries.
We are looking at various Victron Smart batteries or Super pack as house bank.
Appreciate your comments or alternative suggestions.
